just installed mine...love it..the u-tube video doesnt do it justice as i think the car shown isnt running...mine took about 8 seconds going up...now, 3.8 seconds ! Also, my car,being a hybrid, didnt have the curcuit breaker in the normal location...Richard walked me thu what i needed to do...he was busy, but still took the time to call ME back and advise. wish he was closer as he would be doing my next motor.
